php+mysql的日记本

Jun 23, 2016 pm 02:32 PM

花了一天的时间写好了一个用php、mysql的日记本,为了实现分页显示功能花了我一个小时才搞定,编程的思路有点乱,想到哪里就写到哪里,没有具体点的流程设计,所以总有一点小毛病存在。
由于日记的操作在类的定义里都写好了,所以其他文件里对日记操作时很方便,直接调用类里的函数就可以了,包括直接将新日记或修改的日记存到数据库,从数据库中删除,生成xml文件等,一个$diary->****(*)即可。只是不知道使用类到底是不是真的比不用类的速度要慢,网上有写文章里谈到这个问题,并且有比较合理的测试,测试显示两者的速度接近,在一些情况下类还要快点。
关于生成xml文档的函数还是很不完善,如果日记内容里有类似xml标记的东西,一般是不符合xml规范的,不知道如何解决。我想,如果把其中的类似''的东西用转义码代替就可以了,实际上这里生成xml代码时就是这么做的。可惜上我只懂那么一丁点xml,只是知道xml的一点格式要求,看来要更好解决这个问题的话还要去学一下xml了。
由于有一年没写php了,所以现在写时觉得很生疏,有很多东西还要翻书或在网上搜索才能解决。
在win2k下配置了apache+php+mysql服务器,内存使用一下增加了100MB左右,不知道是不是正常。
